   I.   Certain residential subdivisions are subject to the requirements for conservation design. Section 16.76.030 (Conservation Design Triggers) describes those factors that trigger the required use of conservation design. In addition, when the triggers do not apply, an applicant may choose to subdivide their property in accordance with the conservation design requirements. An applicant shall verify that the subject property is not required to undertake conservation design at the time of application for subdivision. A property owner may object to the designation of land as requiring conservation design by demonstrating, through the submittal of an analysis prepared by competent experts, to the Zoning Enforcement Officer, that the property does not meet the triggers for conservation design. If the Zoning Enforcement Officer concurs with the evaluations submitted by the applicant, the conservation design is not required. The County may seek independent expert opinion regarding the analysis and conclusions.
